Vientiane (Lao: ວຽງຈັນ, Viang Chan) is the capital and largest city of Laos, on the banks of the Mekong River near the border with Thailand. Vientiane became the capital in 1563 due to fears of a Burmese invasion. Vientiane was the administrative capital during French rule and, due to economic growth in recent times, is now the economic centre of Laos.
The estimated population of the city is 783,000 (2015). The city hosted the 25th Southeast Asian Games in December 2009 celebrating the 50 years of Southeast Asian Games.
